An Overview of the Use of Bromelain-Based Enzymatic Debridement (Nexobrid®) in Deep Partial and Full Thickness Burns: Appraising the Evidence.

Recent introduction of rapid bromelain-based enzymatic debridement has been increasingly popular in its use in nonsurgical debridement in deep partial and full thickness burns. We designed this study to evaluate the evidence suggested by current studies on the perceived benefits of using Nexobrid® compared with traditional surgical standard of care in burns wound debridement. A comprehensive search on electronic databases Pubmed, Embase, and Web of Science was done to identify studies published between 1986 and 2017 involving the use of Nexobrid® in deep partial and full thickness burns. Studies were evaluated for proposed benefits and categorized under supporting evidence, contradicting evidence, and anecdotal opinions. Seven well-designed prospective studies met the inclusion comprising four randomized controlled trials. Six proposed benefits associated with the use of Nexobrid® were extracted including reduced time to complete debridement, need for surgery, area of burns excised, need for autograft, time to wound closure, and improved scar quality. Most proposed benefits have strong supporting evidences with minimal anecdotal opinions from controlled trials except the proposed improvement in scar quality and reduced time to wound healing that had at least three refuting evidence and one anecdotal evidence. Incidence of pain was also evaluated and was mainly anecdotal lacking formal objective assessment or cohort study. Despite the lack of literatures available, the benefits of Nexobrid® are evident in published randomized and single arm studies. Large number of studies is needed to aid further evaluating the proposed benefits of Nexobrid®.
